Texas Instruments LM4946SQ/NOPB

The LM4946 is an audio power amplifier capable of delivering 540mW of continuous average power into a mono 8Ω bridged-tied
load (BTL) with 1% THD+N, 35mW per channel of continuous average power into stereo 32Ω single-ended (SE) loads with 1% THD+N,
or an output capacitor-less (OCL) configuration with identical specifications as the SE configuration, from a 3.3V power supply.

The LM4946 has three input channels: one pair for a two-channel stereo signal and the third for a differential single-channel
mono input. The LM4946 features a 32-step digital volume control and eight distinct output modes. The digital volume control,
3D enhancement, and output modes (mono/SE/OCL) are programmed through a two-wire I
2C or a three-wire SPI compatible interface that allows flexibility in routing and mixing audio channels.

The LM4946 is designed for cellular phone, PDA, and other portable handheld applications. It delivers high quality output
power from a surface-mount package and requires only seven external components in the OCL mode (two additional components
in SE mode).
